Re: D-link DFE-580TX: Drivers not working on newer versions of Ubuntu
I don't know the answer, but I noticed that your post fell down quite a bit with no answer, so I'll take an educated guess. I believe your 580TX use the driver sundance. Please verify with:
Code:
sudo lshw -C network
Does it say driver=sundance? If so, I saw this (old) post: http://blog.gmane.org/gmane.linux.dr...month=20070701 It is titled Linux 802.1Q a.k.a VLAN (Virtual LAN) kernel driver
From what I read, I guesss the vlan on sundance is software only, and need a special MTU of 1504. Most gigabit cards (not all!) already strip the vlan tag, so the driver only sees a payload of 1500 and somewhere else in the receiver buffer the vlan tag is found.
<snip>
I've been using vlans since 2.4.14 or so, and I have never had to set the MTU size to 1504 for any of my cards. I do know however that some of the drivers need the MTU size of 1504 to keep it from discarding it as a long packet and to cope for the increased buffer size needed.
I wonder if it might help to add to your /etc/network/interfaces:
Code:
auto eth2
iface eth2 inet static
address whatever.108
netmask 255.255.2xy.0
gateway whomever.1
mtu 1504
If sundance is not the driver or if I am on the wrong path, please feel free to advise me.
